 The Muslim city of Yifat was conquered by Ethiopia in 1270, under Yekuno Amlak, which caused officials in Cairo to use their influence to prevent a new bishop from being sent to Ethiopia.This action crippled the Ethiopian Church as well as the power of the emperor.By the time that Amda Siyon (r. 1314-1344) took the throne in 1314, Sabradin of Yifat led a united Muslim front made up of people angered by Christian rule, destroying churches in Ethiopia and forcing Christians to convert to Islam.
